Question
1.
Which of the following is NOT a feature of the proximal end of the ulna?
ulnar notch
semilunar notch
ulnar tuberosity
coronoid process
2.
Which of the following muscle/attachment pairs is correct?
adductor magnus / deltoid tubercle
sartorius / patella
biceps brachii / radial tuberosity
short head biceps brachii / supraglenoid tubercle
3.
In constructing a muscle from the smallest element to the largest, this sequence of terms is correct.
myofilament, myofibril, myofiber, fascicle
fascicle, myofilament, myofiber
endomyseum, perimyseum, epimyseum
myomeseum, perimyseum, fascia
a.ulnar notch
b.semilunar notch
c.ulnar tuberosity
d.coronoid process
Explanation / Answer
1.answer is a. ulnar notch
The proximal end of the ulna articulates with the trochlea of the humerus. Important landmarks of the proximal ulna are the olecranon, coronoid process, trochlear notch, radial notch and the tuberosity of ulna:
2. c. biceps brachii and radial tuberosity is the correct pair.
a.The adductor part attaches distally to the linea aspera, the gluteal tuberosity on the femur and the medial supracondylar line on the distal femur.
b.Sartorius muscle,long, narrow, ribbonlike thigh muscle beginning at the front of the crest of the pelvic girdle, extending obliquely down the front and side of the thigh, and inserted at (attached to) the inner and upper portion of the tibia (shinbone).
c. & d. Origin: (proximal attachments)
a. Long head: supraglenoid tubercle of the scapula.
b. Short head: coracoid process of the scapula.
Insertion: (distal attachments)
a. Radial tuberosity.
b. Bicipital aponeurosis to the fascia on the medial side of the forearm.
3.a.myofilament ----myofibril----myofiber---fascicle
